Zusammenfassung:
The aerodynamic interference between main rotor and fuselage of a helicopter is investigated experimentally with the help of time averaged pressures measured on the fuselage surface. A total of 450 pressure taps were distributed over the fuselage surf ace in regions where the interference effects were expected to be severe. The facility used was a 1:6.5 geometrically scaled down model of BO 105 helicopter operated in open test section of DLR 3.25 m x 2.8 m subsonic wind tunnel in Braunschweig. The rotor of the model has a diameter of 1. 5 m and is roach-scaled. Parameters varied are thrust ratio, advance ratio and fuselage incidence. Some global flow visualization with smoke filaments was also performed.
